Abstract
The nonlinear behavior of electrohydrodynamic convection in planarly aligned nematic liquid crystals is reviewed. Based on two-dimensional, universal envelope descriptions we present new results on undulated roll structures in the vicinity of a normal-to-oblique roll transition, wavelength selection by the Eckhaus processes, dynamics and ordering of defects in travelling roll patterns (also applicable to homogeneous Hopf bifurcations), and mean-flow induced turbulence.
